How can I distribution to multiple addresses at a time? [duplicate]

Question

This question already has an answer here:

• Distribute token to multiple address 1 answer

I have a contract now distributing the tokens but I'm tired of sending individually. Can I get the solidity code to simply send to many addresses? Edited:::: In brief about the question 1.I want to send the same number of tokens to multiple addresses. Help me with the complete contract code not that single function :( .

This code seems working to me but i am bit confused 1.First do i need to create the contract and then send tokens to the created contract address and then give the values addresses and number of tokens and then click on sendTokenSingleValue area? please guide me

pragma solidity ^0.4.16;

contract Ownable {

  address public owner;

  function Ownable() {
    owner = msg.sender;
  }

  modifier onlyOwner() {
    require(msg.sender == owner);
    _;
  }

  function transferOwnership(address newOwner) onlyOwner {
    require(newOwner != address(0));
    owner = newOwner;
  }
}

interface Token {
  function transfer(address _to, uint256 _value) returns (bool);
  function balanceOf(address _owner) constant returns (uint256 balance);
}

contract AirDrop is Ownable {

  Token token;

  event TransferredToken(address indexed to, uint256 value);
  event FailedTransfer(address indexed to, uint256 value);

  modifier whenDropIsActive() {
    assert(isActive());

    _;
  }

  function AirDrop () {
      address _tokenAddr = 0x; //here pass address of your token
      token = Token(_tokenAddr);
  }

  function isActive() constant returns (bool) {
    return (
        tokensAvailable() > 0 // Tokens must be available to send
    );
  }
  //below function can be used when you want to send every recipeint with different number of tokens
  function sendTokens(address[] dests, uint256[] values) whenDropIsActive onlyOwner external {
    uint256 i = 0;
    while (i < dests.length) {
        uint256 toSend = values[i] * 10**18;
        sendInternally(dests[i] , toSend, values[i]);
        i++;
    }
  }

  // this function can be used when you want to send same number of tokens to all the recipients
  function sendTokensSingleValue(address[] dests, uint256 value) whenDropIsActive onlyOwner external {
    uint256 i = 0;
    uint256 toSend = value * 10**18;
    while (i < dests.length) {
        sendInternally(dests[i] , toSend, value);
        i++;
    }
  }  

  function sendInternally(address recipient, uint256 tokensToSend, uint256 valueToPresent) internal {
    if(recipient == address(0)) return;

    if(tokensAvailable() >= tokensToSend) {
      token.transfer(recipient, tokensToSend);
      TransferredToken(recipient, valueToPresent);
    } else {
      FailedTransfer(recipient, valueToPresent); 
    }
  }   


  function tokensAvailable() constant returns (uint256) {
    return token.balanceOf(this);
  }

  function destroy() onlyOwner {
    uint256 balance = tokensAvailable();
    require (balance > 0);
    token.transfer(owner, balance);
    selfdestruct(owner);
  }
}

when i tried with this code i got this error? what to do ? transact to browser/ballot.sol:AirDrop.sendTokensSingleValue errored: Gas required exceeds limit: 3000000. An important gas estimation might also be the sign of a problem in the contract code. Please check loops and be sure you did not sent value to a non payable function (that's also the reason of strong gas estimation).

Answer 1

Check this and/or this as they already have the solutions. Either of this should work for you.
